Abstract: A transport refrigeration unit (TRU) includes a compressor. The TRU further includes a condenser disposed downstream of the compressor. The TRU further includes an expansion device disposed downstream of the condenser. The TRU further includes a first flow control device disposed downstream of the condenser. The TRU further includes a first evaporator disposed downstream of the expansion device and the first flow control device. The first evaporator is disposed upstream of a second flow control device. The second evaporator is disposed downstream of the first flow control device, the expansion device, and the second flow control device. The second evaporator includes a thermal accumulator. The second flow control device disposed upstream of the compressor.

Abstract: A vehicle including a roof that separates an exterior and an interior of the vehicle, and an air conditioning system. The roof has an exterior surface, an interior surface, and an aperture extending through the roof between the exterior surface and the interior surface. The air conditioning system includes an exterior housing that is mounted to the exterior surface of the roof and includes a divider defining a first cavity, and a second cavity. The air conditioning system also includes a condenser, an evaporator, and an evaporator blower. The air conditioning system further includes an interior housing that is removably mounted to the interior surface of the roof and defines a mounted position and a removed position in which the evaporator and evaporator blower are accessible for servicing from the interior of the vehicle.

Abstract: A vehicle may include a roof and an air conditioning system. The roof may have an exterior surface, an interior surface, and an aperture extending through the roof between the exterior surface and the interior surface. The air conditioning system may include an exterior housing that is mounted to the exterior surface of the roof. The air conditioning system may also include an evaporator and an evaporator blower. The air conditioning system may further include an interior housing that is removably mounted to the interior surface of the roof and defines a mounted position and a removed position. When the interior housing is in the removed position, the evaporator and evaporator blower may be accessible for servicing from the interior of the vehicle.
